Summary
In the new 1.19 update downloading a csv file is not showing up as a .csv file but just as a “file”.
Steps to reproduce
Code snippet:
import pandas as pd
import streamlit as st
def convert_df(df):
"""
converts df to csv
:param df: df to make csv
:return: df in csv
"""
return df.to_csv(index=False)
def download_button(filename, data):
st.download_button(
label="Download Output File",
data=data,
file_name=filename,
mime='text/csv',
)
df = pd.DataFrame([1, 2, 3])
converted_df = convert_df(df)
download_button('testdf', converted_df)
I am expecting a csv file, not a “file”.
Debug info
- Streamlit version: ‘1.19.0’
- Python version: 3.10.6
- Pandas version ‘1.4.3’
Prior to this version it was working fine.
